"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: avoid too many retransmit packets\n\nIf a TCP socket is using TCP_USER_TIMEOUT, and the other peer\nretracted its window to zero, tcp_retransmit_timer() can\nretransmit a packet every two jiffies (2 ms for HZ=1000),\nfor about 4 minutes after TCP_USER_TIMEOUT has 'expired'.\n\nThe fix is to make sure tcp_rtx_probe0_timed_out() takes\nicsk->icsk_user_timeout into account.\n\nBefore blamed commit, the socket would not timeout after\nicsk->icsk_user_timeout, but would use standard exponential\nbackoff for the retransmits.\n\nAlso worth noting that before commit e89688e3e978 (\"net: tcp:\nfix unexcepted socket die when snd_wnd is 0\"), the issue\nwould last 2 minutes instead of 4."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tcp: evitar demasiados paquetes de retransmisi\u00f3n Si un socket TCP est\u00e1 usando TCP_USER_TIMEOUT y el otro par retrajo su ventana a cero, tcp_retransmit_timer() puede retransmitir un paquete cada dos santiam\u00e9n (2 ms). para HZ=1000), durante aproximadamente 4 minutos despu\u00e9s de que TCP_USER_TIMEOUT haya 'expirado'. La soluci\u00f3n es asegurarse de que tcp_rtx_probe0_timed_out() tenga en cuenta icsk->icsk_user_timeout. Antes de el commit culpable, el socket no expiraba despu\u00e9s de icsk->icsk_user_timeout, sino que usaba un retroceso exponencial est\u00e1ndar para las retransmisiones. Tambi\u00e9n vale la pena se\u00f1alar que antes de commit e89688e3e978 (\"net: tcp: fix unexcepted socket die cuando snd_wnd es 0\"), el problema durar\u00eda 2 minutos en lugar de 4."
